31 Current Trading Schemes... relevant for Compost and soil? Strategies to tackle climate change often do not recognise the potentially important role of LULUCF (Land Use, Land Use Change and Forestry, i.e. farm-and soil-based activities) e.g. EU Emission Trading Schemes (Dir. 2003/87) Excludes C sinks and LULUCF from crediting/trading!! Composting in CDMs? Composting included in CDM schemes by the CDM Board (2005) A standard calculation method to assess GHG savings has been defined Only methane savings from landfills are allowed for, yet No crediting of soil-related benefits Sheet 34
32 Mechanism for monitoring and reporting greenhouse gas emissions a new approach in the EU REGULATION OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on the inclusion of greenhouse gas emissions and removals from land use, land use change and forestry into the 2030 climate and energy framework and amending Regulation No 525/2013 of the European Parliament and the Council on a mechanism for monitoring and reporting greenhouse gas emissions and other information relevant to climate change Article 2 (c) Scope: Accounting for managed cropland, managed grassland and managed wetland Article 5 (4): Member States shall include in their accounts for each land accounting category any change in the carbon stock of the carbon pools listed in Annex I, section B. Annex I - B. Carbon pools pursuant to Article 5(4): (a) above-ground biomass; (b) below-ground biomass; (c) litter; (d) dead wood; (e) soil organic carbon; (f) for afforested land and managed forest land: harvested wood products. 35

36 Are there any good incentives for C-sequestration or humus build-up in Europe? Country Humus build-up program Netherlands Ireland Hungary Austria Italy NO NO EU Structural Fund (Operational Programm Environment covers 40% of eligible costs) is only granted if 50% of the compost is applied on agricultural land based on a mutual contract Only indirect by accepting compost as organic fertiliser within the Agricultural Environment Program (substituting mineral N, biological agriculture) Regional Rural Development Programs dedicated to compost application pay between 78.- and per ha

Raw organic matter shows a high variation of effects In 44% increased decomposition effectuates disease suppression In 23% the opposite is the case Different pathogens react different With ongoing maturation the microbial competition weakens saprophytic pathogens Further mineralisation decreases biodiversity growth conditions for all organisms, thus alsodeminishing the suppressing capacity Bonanomi et al. 2010

64 The Compost Market Is there a demand for compost? A) No real demand in starting countries, because compost products and their benefits are UNKOWN. B) A strongly growing demand in advanced countries with mature and developed markets The amount of produced compost is increasing No marketing problems for quality compost, high demand The development of different compost products leeds to an opening of additional market sectors and demand. Different market sectors have different prices, sometimes quite low, partly quite high (agriculture versus growing media sector)
65 Market of Compost in EU Average price for compost products in EU Prices range from 0-30 per tonne - depending on the feedstock, content of nutrients and quality Average cost for composting in EU: EUR per tonne 69
